ALBERT LEVER-HANDLE FOR DOOB-LATCHES.

To all whom it may concern:

Be it'known that I, ALBERT A. PAGE, of the town of East Haven, county ofNew Haven, and State of Connecticut, have invented new and usefulImprovements in Lever-Handles for Door-Latches, of which the followingis a-full, clear, and exact description when taken in connection withthe accompanying drawings, which form a part thereof. I

My invention relates to .lever handles ror door latches, and'itsobject-is provide means to compensate for the weight of the handle andinsure effectively the retract on of the handle when used in conjunctionwith the ordinary retracting spring of the latch bolt.

With this end and others in. view, my invention is embodied inpreferable form in the device hereinafter described and illustrated inthe drawings.

In these drawings, Figure 1 is a front view in elevation of anescutcheon in which the lever handle is mounted, and of a casing showingpart of the latter broken away, for the purpose of illustrating thelatch bolt and its spring Fig. 2 is a section through the escutcheon online w m, Fig. 1. Fig. 3 is an edge view of; he stop members forlimitingthe movement of ,the lever handle, and Fig. 4 is a view of theinnercnd of the shank with the locking nut removed.

In all figures, similar letters of reference re resent like parts.

.er'erring to the drawing, 1 is a suitable escutchcon mounted on theface of the door, and carrying an outwardly projecting rose 2. A leverhandle 3 has a shank 4, which Specification of Letters Patent.

extends through, and is jouriialcd in the rose, and the inner end of theshank 4 is adapted to retract a latch bolt 7 of the ordinary type bymeans such as a spindle (not shown), connected with the usual hub orroll-back, and fitting in a squared recess 4 at the inner extremity. ofthe shank 4. The latch bolt 7 is normally held in protracted osition bysprings 8, 8' acting on the latch Bolt shank and yoke, respectively, andtending to hold the lever handle in the normal horizontal position shownin Fig. l.

Owing to the weight of the lever handle and the fact that such weight isdisposed to one side of the center of rotation of the spindle, it isfrequently found that the ordinary latch bolt spring, such as 3', isin-Patented Jan. 21, 1913.

Serial no. 637,639.

adequate to hold the lever handle in its normal inoperative position. Toovercome this difiiculty, and to provide an effective means formaintaining normal position and for returning it thereto after it hasbeen operated to retract the latch bolt, and at the same time to effectsuch Oujtct without the necessity of the employment'of additionalsupporting means, a spiral spring 9 is used, which spring is mountedwithin the rose 2 of the escutcheon and surrounds the shank 4 of thelever han dle. One end of this spiral spring is secured to the shank andthe other end to the base of the rose, whereby upon moving the the leverhandle in handle downward the spring will tend to restore the handletoits normal horizontal position. The base of the rose, to which thespring is preferably connected, conforms closely to the shank and issecured in an appropriate opening in the esciitcheon, as shown in Fig.2.

On the inner face of the escutcheon surrounding the opening throughwhich the handle shank asses is fixed a collar 10 cut away to provir e ashoulder ll against which is adapted to abut the shoulder 12 of acircular stop member 13 carried by the shank. The stop member 13 hasinner angular walls 14 adapted to engage squared or angle faces 15formed on the shank, whereby the stop member is held from rotation onthe latter. A lock nut 16 is screwed on the shank beyond the stop member13. In the normal position of the lever handle, the shoulders of therespective stop members are separated and upon moving the lever handledownward so as to retract the latch bolt the handlc will be permitted tomove until the shoulder of the stop member 13 strikes against theshoulder of the fixed collar 10.

It will be seen that the arrangement above described provides a meansauxiliary to the latch bolt spring for insuring the eiiective return ofthe lever handle to normal position, and at the same time this object isattained in a compact assemblage of parts,

specific form and mounting of the spring,

while in other aspects of the invention I do not limit myself to thespecific arrangement of the stop means.

Having thus described my invention, what I claim and desire to secure byLetters Patcut, is

1. In a handle device for door latches, the combination with a latchbolt; of a protracting spring for said latch bolt; a lever handle; anescutcheon mounted on the door and having an apertured rose lnto whichthe shank of said lever handle pro ects; and

a spiral spring confined within said rose and having one end secured tothe shank and the other end to the rose, said spring acting to returnthe lever handle to normal inoperative position; substantially asdescribed.

2. In a handle device for-door latches, the combination of anescutcheon, a latch-manipulating device having a shank extending throughsaid escutcheon, a spring acting on said device to normall hold. it in apredetermined position, a ed shouldered stop collar embracing said shankat the inner face of the escutcheon, and a stop member secured to ahdembracing the inner end portion of said shank, and having a shouldercooperating with the shoulder of said collar; substantially asdescribed.
